2013-04-29TBAA: remove !tbaa from testing cases if not used.Manman Ren
This will make it easier to turn on struct-path aware TBAA since the metadata format will change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180743 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-13MemoryDependenceAnalysis attempts to find the first memory dependency for ↵Nadav Rotem
function calls. Currently, if GetLocation reports that it did not find a valid pointer (this is the case for volatile load/stores), we ignore the result. This patch adds code to handle the cases where we did not obtain a valid pointer. rdar://11872864 PR12899 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161802 91177308-0d34-0410-b5e6-96231b3b80d8
